Java毕业设计实战之在线高中考试系统的实现

更新时间：2022年02月05日 14:21:55 作者：qq_1334611189

这是一个使用了java+SSM+Jsp+Mysql+Maven开发的在线高中考试系统，是一个毕业设计的实战练习，具有考试系统该有的所有功能，感兴趣的朋友快来看看吧

项目分为前台和后台，前台主要为学生角色、后台主要为管理员角色。

管理员添加试题和发布试卷，学生负责在线考试、在线查看成绩和错题记录列表等。

管理员功能有：年级管理、课程管理、试题管理、试卷管理、学生管理等。

运行环境：jdk1.8、mysql5.x、eclipse、tomcat8.5\7.0、maven3.5\3.6。

统一管理学生教师管理员信息：

/**
 * 统一管理学生 教师 管理员信息
 */
@RestController
public class UserController {
 
    @Resource(name = "userService")
    private IUserService userService;
 
    /**
     * 查询用户信息
     * 先判断用户类型 在查询用户信息
     */
    @RequestMapping(value = "/user/qryUserInfo", method = RequestMethod.POST, produces = {"application/json;charset=UTF-8"})
    public Result<User> qryUserInfo() {
        return userService.qryUserInfo();
    }
 
    /**
     * 更新用户信息
     */
    @RequestMapping(value = "/user/update", method = RequestMethod.POST, produces = {"application/json;charset=UTF-8"})
    public Result<User> update(HttpRequest request) {
        User user = new User();
        user.setUserId(request.getString("user_id"));
        user.setName(request.getString("name"));
        user.setSex(request.getInteger("sex"));
        user.setType(User.UserType.get(request.getInteger("type")));
        return userService.update(user, ImageUtil.stringToBytes(request.getString("user_image")));
    }
 
    /**
     * 更新用户密码
     */
    @RequestMapping(value = "/user/updatePwd", method = RequestMethod.POST, produces = {"application/json;charset=UTF-8"})
    public Result<User> updatePwd(HttpRequest request) {
        return userService.updatePwd(request.getString("old_pwd"), request.getString("pwd"));
    }
}

管理员控制器：

/**
 * 管理员控制器
 */
@RestController
public class AdminController {
 
    @Resource(name = "adminService")
    private IAdminService adminService;
 
    /**
     * 管理员 查询管理员列表
     */
    @RequestMapping(value = "/admin/qryPage", method = RequestMethod.POST, produces = {"application/json;charset=UTF-8"})
    @RoleAnnotation(types = {RoleEnum.admin})
    public ListResult<Admin> qryPage(HttpRequest request) {
        Map<String, Object> param = new HashMap<>();
        int pageNo = request.containsKey("page_no") ? request.getInteger("page_no") : 1;
        int pageSize = request.containsKey("page_size") ? request.getInteger("page_size") : 20;
        if (request.containsKey("login_name")) {
            param.put("login_name", request.getString("login_name"));
        }
        if (request.containsKey("name")) {
            param.put("name", request.getString("name"));
        }
        return adminService.qryPage(param, pageNo, pageSize);
    }
 
    /**
     * 管理员 添加管理员
     */
    @RequestMapping(value = "/admin/add", method = RequestMethod.POST, produces = {"application/json;charset=UTF-8"})
    @RoleAnnotation(types = {RoleEnum.admin})
    public Result<Admin> insert(HttpRequest request) {
        Admin admin = new Admin();
        admin.setLoginName(request.getString("login_name"));
        admin.setName(request.getString("admin_name"));
        admin.setPwd(request.getString("login_name"));
        admin.setSex(request.getInteger("sex"));
        admin.setUpdateTime(new Date());
        return adminService.insert(admin, ImageUtil.stringToBytes(request.getString("admin_image")));
    }
 
    /**
     * 管理员 更新管理员
     */
    @RequestMapping(value = "/admin/update", method = RequestMethod.POST, produces = {"application/json;charset=UTF-8"})
    @RoleAnnotation(types = {RoleEnum.admin})
    public Result<Admin> update(HttpRequest request) {
        Admin admin = new Admin();
        admin.setLoginName(request.getString("login_name"));
        admin.setName(request.getString("admin_name"));
        admin.setPwd(request.getString("login_name"));
        admin.setSex(request.getInteger("sex"));
        admin.setUpdateTime(new Date());
        return adminService.update(admin, ImageUtil.stringToBytes(request.getString("admin_image")));
    }
 
    /**
     * 管理员 删除管理员
     */
    @RequestMapping(value = "/admin/del", method = RequestMethod.POST, produces = {"application/json;charset=UTF-8"})
    @RoleAnnotation(types = {RoleEnum.admin})
    public Result<Admin> del(HttpRequest request) {
        List<String> adminIdList = new ArrayList<>();
        JSONArray array = request.getJSONArray("admin_id_list");
        for (int i = 0; i < array.size(); i++) {
            adminIdList.add(array.getString(i));
        }
        return adminService.del(adminIdList);
    }
}
